Özet: There are some hypotheses to explain the cause and maintenance mechanisms of differences between the sexeswith species. Among these mechanisms sexual selection, competition for food researches, female reproductionstrategy and energy requirement for reproduction will be reviewed in the fi rst part of the study. Differencesbetween the sexes provide a reproduction advantage to the individual. On the other hand, sexual dimorphism maycause some disadvantages directly to the ornamented individual or indirectly to its partner. The disadvantages ofthe sexual dimorphism will be discussed in the second part of the study. Types of the sexual dimorphism, whichare ranging from size to behavior either common to most of the animal species or unique for some of the species,will be reviewed in the last part of the study.
